L band

L band, as defined by the IEEE, is the 1 to 2 GHz range of the radio spectrum.

Applications

Mobile service

In Europe, the Electronic Communications Committee (ECC) of the European Conference of Postal and Telecommunications Administrations (CEPT) has harmonized part of the L band (1452-1492 MHz), allowing individual countries to adopt this spectrum for terrestrial mobile/fixed communications networks supplemental downlink (MFCN SDL). By means of carrier aggregation, an LTE-Advanced or UMTS/HSDPA base station could use this spectrum to provide additional bandwidth for communications from the base station to the mobile device, i.e. in the downlink direction.

Radionavigation-satellite service

The Global Positioning System carriers are in the L band, centered at 1176.45 MHz (L5), 1227.60 MHz (L2), 1381.05 MHz (L3), and 1575.42 MHz (L1) frequencies.

  • The Galileo Navigation System uses the L band similarly to GPS.
  • The GLONASS System uses the L band similarly to GPS.
  • Telecommunications use

    L band (NATO)

    The NATO L band is the obsolete designation given to the radio frequencies from 40 to 60 GHz (equivalent to wavelengths between 7.5 and 5 mm) during the cold war period. Since 1992 frequency allocations, allotment and assignments are in line to NATO Joint Civil/Military Frequency Agreement (NJFA).

    However, in order to identify military radio spectrum requirements, e.g. for crises management planning, training, Electronic warfare activities, or in military operations, this system is still in use.

    L band (disambiguation)

    L band may be used to designate one of four different bands of the electromagnetic spectrum:

  • 1 to 2 GHz: L band, as defined by the IEEE
  • 40 to 60 GHz, L band (NATO) as defined by NATO for ECM systems. See EU, NATO, US ECM frequency designations
  • 3.5 micrometres, an atmospheric transmission window used in infrared astronomy
  • 1565 nm to 1625 nm, a transmission window in fiber-optic communication

  • +/- (band)

    +/-, or Plus/Minus, is an American indietronic band formed in 2001. The band makes use of both electronic and traditional instruments, and has sought to use electronics to recreate traditional indie rock song forms and instrumental structures. The group has released two albums on each of the American indie labels Teenbeat Records and Absolutely Kosher, and their track "All I do" was prominently featured in the soundtrack for the major film Wicker Park. The group has developed a devoted following in Japan and Taiwan, and has toured there frequently. Although many artists append bonus tracks onto the end of Japanese album releases to discourage purchasers from buying cheaper US import versions, the overseas versions of +/- albums are usually quite different from the US versions - tracklists can be rearranged, artwork with noticeable changes is used, and tracks from the US version can be replaced as well as augmented by bonus tracks.
